IP address assignment

About IP address assignment

If you are applying for a Janet Network connection, we can assign an IP address space to your organisation from those allocated to Jisc for use over the Janet Network.

There are a number of approaches to IP addressing:

Providing IPv6 address spaceJanet's network backbone is fully enabled for IPv6. If you have a Janet connection, the IPv6 address space is available to you free of charge

Private IP4 address space and network address translation (NAT)If you are using IPv4 address space, NAT makes the best use of small blocks of addresses allocated from the globally unique IP address space, and assists in conserving this limited resource

IP subnet addressingMakes better use of IP address space; allows IP addresses to be divided into multiple smaller networks or subnets. Effective use of subnets may remove the need to obtain additional address space

IPv6 address space assigned from within the Janet 2001:0630::/32 prefix
